Havasupai Falls

The stream flow data in this briefing is from California USGS gauges (Salinas River, Llagas Creek, Alameda Creek) — none of these are Havasu Creek or Cataract Creek. That data is irrelevant to your trip and should be disregarded entirely. For actual Havasu Creek conditions, check the USGS gauge 09404900 (Havasu Creek near Supai) directly before you leave, or contact the Havasupai Tribe tourism office. Early November is typically a stable, low-flow period for Havasu Creek — monsoon season is over and snowmelt hasn't started — but always verify before committing to the canyon.

Weather is about as good as it gets for this trip. Highs of 63–65°F, lows around 40–41°F, light winds under 7 mph from variable directions, and sunny to partly sunny skies through Wednesday. No precipitation in the forecast. The canyon walls will stay warm through midday. Nights at the campground will be cool but not cold — standard fall layering handles it. No weather risk this window.

Daylight is the one operational constraint worth planning around. Sunrise at 6:55 AM and sunset at 5:35 PM gives you 10 hours 40 minutes, and the canyon rim blocks light earlier than the official sunset time suggests. The standard hike-in from the Hualapai Hilltop trailhead is 10 miles and 2,000 feet down — most parties take 3.5 to 5 hours. If you're starting today, get on the trail by 8 AM at the latest to reach Supai Village with comfortable daylight buffer before the 2-mile push to the main campground. On the way out, start your ascent no later than 9 AM to clear the exposed upper trail before early afternoon heat and guarantee you're back at the rim well before 5:35 PM.

No fires within 50 miles, no avalanche terrain, zero snowpack at relevant elevations. Air quality will be clean. This is a straightforward weather window — your only homework before leaving is confirming Havasu Creek flows directly from USGS or the tribe.
